ATCP 93.410(1)(a)
(a) All aboveground storage tanks, whether new or existing, shall have a means of overfill prevention which consists of either a visual gauge, an audible or visual alarm, or a pump shutdown that activates at 90 percent of the tank's capacity, and which complies with any other applicable requirements in this section.
ATCP 93.410(1)(b)
(b) Prior to delivery, the operator of the product delivery equipment that is transferring the product shall ensure that the volume available in the tank is greater than the volume of product to be transferred to the tank.
ATCP 93.410(2)
(2) The transfer operation shall be monitored constantly by the operator of the delivery equipment so as to prevent overfilling and spilling.
ATCP 93.410(3)
